the best thing to do is react appropriately to their def of PvP. You're not going to change anyone's mind about what PvP is...everyone has their own opinion.
if they gank you, eat it and roll. no tears = no victory. if they decide to camp you, log an alt. let them sit there twiddling their thumbs for as long as it takes them to realize you're not coming back anytime soon.
PvP is also a psychological war to some...when you complain, they've already won.
